Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25588, here are decompositions:

5 + 25583 = 25588
11 + 25577 = 25588
47 + 25541 = 25588
131 + 25457 = 25588
149 + 25439 = 25588
179 + 25409 = 25588
197 + 25391 = 25588
239 + 25349 = 25588

Showing the first eight; more decompositions exist.
